What happens
On Euclidea, scientist Kiyops and his companion Thales test a rocket plane carrying Captain Bradford and Jerry Hall. Instrument trouble drives them past their fuel limits, and the plane falls toward the sea. Captain Bradford takes the controls and manages a risky dive that brings the craft down onto the water. Radio contact is made with the underwater city, and Commander Strah sets out in a submarine to tow them in. Magic Island is the series, and the episode's original air date and cast are not given in the transcript.

Written from the episode itself; it never gives away the ending. Every recording is remastered for the stream: cleaned of rumble, hiss and mains hum (and the old TV whine where we found it), then levelled in two passes to steady broadcast loudness, so one show is never quieter than the next.
